Application filed August 3, 1906. Serial No. 329,004.

and for various purposes, it is here ill'ustrated as applied to a trackchanneling machine constructed not only for cutting the usual channelgroove, butspecially adapted for corner-cutting, that is, the cutting.of the channel groove into the acute angle or corner underlying theinclined side of a quarry wall.

In the specific embodiment of our invention the corner-cutting iseffected by so mounting the tool support that, whileopcrating as usualin'the open part of the quarry it may be made to out from a fixedposition of the machine under the overhanging side-walls while the toolswings along the arc of a circle lengthening the channel groove,delivering'its blows perpendicularly to the bottom of the groove andthereby losing none of theefi'ectiveness of its cutting stroke.

Our invention, having as it does other objects both connected with anddisconnected from the above-mentioned aim, will be best understood by[reference to the following description, when taken in connection withthe accompanying illustration of one ,spe cific embodiment thereof,while its scope will be more particularly pointed out in the appendedclaims: I

In the draw1ngs:Figure;1 isa central transverse sectional elevation of.a channeling machine embodying one form of'our in vention; Fig. 2 aview, diagrammatic its nature, showing themanner in which the,

{machine may be used for corner-cutting; Fig. 3 is. a front elevation ofthe channeling machine shown in Fig. 1, Fig.4isfa plan view takensection on the irregular section line in Fig. 1, and Fig. 5 is asectional detailon the line 5-5, Fig. 3, show lng the locking pin.

Referring to the drawings and to the embodiment of our invention theresubmitted for illustrative purposes, the track channeling machine thereshown is supported upon a frame work A which has journaled at oppositeends'the two transverse shafts a, carrying at their outer ends two pairsof flanged trucks a, the latter tracking with the rails 72, which arecustomarily laid upon the quarry bottom, and along which the machine,when cutting in the usual fashion 1 is advanced. y c

The machlne carries suitable tool-reciproeating motive means, which maybe of any suitable form but whlch is here shown as a.

compressed. air direct acting engine, suppl ed with pressure from asuitable source (not shown) and having the piston c, cylinderC and thecross-head guides D. The,

cross-head E, which is connected to the piston by the piston-rod 0, hasclamped thereto a suitable tool or tools, such as the gang 6 of threechanneling tools shown.

partly broken away, the cutting ends of the latter, therefore, beinggiven a reciprocatory' cutting movement to and from the bottom of thechannel groove with the reciprocations of the engine piston. Foradjustably feeding the tool toward the work as the channel groovedeepens the engine cylinder and cross-head guides which are connectedtomove as an unit, are carried by the cutter head or standard F, and maybe advanced along its face by means of the fixed nut c on the cylinderand engaged by the longitudinal adjusting screw c which latter at itsupper end'is journaled in an extension f of the cutterhead.

The cutter-head (Fig. 4) is provided with suitable guiding ribsorflanges f on which the engine cylinder and the attachedcrossheadguides are slidably retained by the gibs f and along which they may beadjusted longitudinally'by the adjusting screw 0 f The latter at itsupper end is provided with a head f through which, by the attachment ofa suitable tool or implement,

such as the ratchet lever" f (Fig. 1), the screw may be turned vand theengine and cross-headadvanccdtoward the work as the channel groovedeepens.

To obtain the swinging movement of the tool lengthwise the channelgroove during .corner cutting, the cutter-head F,.-is' supported at theside of the machine upon an oscillating or swinging support G, thelatter comprising a circular plate or casting, having formed in its face(Figs. 3 and 4) a longitudinal guideway, in which the standard isadjustably clamped by means of the clamping-plates 7, which are boltedto the plate G. The clamping-plates hold the r v standard in fixedposition, but the clamping- 'bolts may be loosened to permit it to beadjusted longitudinally, so that the entire standard with its attachedcutting appliances may be dropped or advanced toward the work andclamped in .this advanced po- 'sition, as represented forexample in Fig.2. The clamping-plates preferably extend, as shown, across the entireface of the supporting plate G, so that when the standard is adjusted toa more advanced position it is maintained in accurate alinement withreference to the center of the plate, the axis of tool action lyingpreferably across the oscillation center of the plate.

In order to provide I an oscillating or swinging movement for thecutter-head and thetool when the machine is employed for corner-cutting,the support G ismounted to swing through any desired arc in the mainfsupporting-'frame H, which latter is mount ed at the side. of the,machine, as shown in Fig. 1. To permit the oscillating movement of thecutting parts the plate G has the centrally formed trunnion 9' journaled in a I bearing 71. formed in the-frame H, the said bearingbeing providedwith the removable lining h. The plate'is held in positionby the cap 9., fastened to the' trunnion by the bolt g? and preventedfrom turning thereon by the pin 9 r When angle-cutting is desired, themain frame .H, is adjustable about an axis lengthwise the channel grooveso that it may be inclined backward, away from the vertical.

, To permit'this adjustment it is fixedly secured at its base totrunnions 72 j ournaled in the main frame A. Itlis held fixed in either.an upright or an inclined position as maybe desired during cutting byany suitable means, such as the inclined brace-rod I, the latter linkedat itsupper end to an ear 72. upon the back of the frame H and at itslower end to an ear 2' carried by a" bracket i removably bolted to aseat upon v, the main frame A. The brace-rod I is formed in'twoseparatepiecesand provided with a suitable turnbuckle connection 2' by 7 meansofwhich its length may be taken up or extended to permit the necessaryadjustw ment of the supporting-frame.

7 For reciprocating or oscillating the cutterhead during cornercutting,the back of the oscillating plate bolted to; a cir- 1,1so,6eo

cular actuating device such as the'annular worm gear J, meshing with anunderlying driving worm j, the. axis of-the latter being coincident withthe swinging axis of the frame 11, so that the worm remains in propermesh with its gear irrespective of the adjustment of theplate upon the,trun- 'nions' 71. The back face of the plate G near its edges has asliding'contact with the main supporting frame H at if, so that there isformed, in effect, a housing for the worm 7 gear, protecting the latterfrom dust and dirt. V

- washers may be taken up, a suitable checknut 'lc beingprovided to lockthe same into position. V I 7 'Any suitable pmeans either manual orpower driven for giving reciprocating driv-- ing movement to the wormgear J may be employed, but herein we have shown a special motive devicecomprising the tool-actuating fluid pressure engine L which turns thetransverse driving-shaftl. The engine (not shown) and iscontrolled as tospeed by V *the'throttlevalve Z (Fig. 4). The transverse shaft 1 carriesat its 'end the beveled pinion m, which imparts opposite but equalrotation tothe two beveled gearsm and, m These may be separatelyclutched to or unclutched from the clutch-shaft m by the slidifi'gmovement of the double clutch-member m*. The movement of the latter iseffected through the shifting actuator m (shown only in Fig. 4 connectedto the hand-lever m", the handle of which is conveniently positioned forgraspby the operator.. The clutch member may be shifted by .thehand-lever to clutch either the gear m or the gear m to the shaft m orleft 7 in an intermediate position wherein neither gear, engages theshaft and'the latteroremains stationary. r

The shaft m? has a pinion m which meshes with the gear, m on thecountershaftmflthe latter journaled in a bracket m? onthefmachine'frame. The counter-. shaft also carries a gear m, meshingwith the [idle gear m the latter engaging directly with the gear 111.which is fast upon andacts to drive directlythe worm-shaft j.

.13)? .1 9 .dmclfi ed transmission earing th 100 p is connected by thefiexiblehoseconne'ction Z .to the source of compressed air supplytool-actuating engine L, when in operation, turns the worm-shaft andcauses a comparatively slow swinging movement of the cutter-head uponits trunnion simultaneously With the rapid chopping action of the toolunder the influence of the stool engine C. When the swinging movementhasadvanced far enough in one direction the actuator m may be thrown andthe swinging movement reversed. A power actuation of the swing ingsupport is preferable sinceit not only renders the machine moremechanical but better insures a uniform swinging move ment and thepreservation therefore of a true are at the bottom of the channelgroove.

During the cutting of the ordinary channel groove the channeler iscaused to traverse the trackway as usual and the cutter head is heldfixed in the usual fashion. To throw out the oscillating movement of thecutter-head under such conditions the idle gear m is slidably mounted onthe stud m, so that, when desired, it may be slipped out of mesh withits two engaging gears m and m, and thetransmission gearing therebythrown out of engagement. This leaves the cutter-head fixed in position,the worm holding it against movement. If desired, a locking-pin h (Fig.3) may be used to effectually lock the swinging plate against movementrelatively to the sup porting-frame H.

During the cutting of the ordinary chan nel groove the necessarytraversing move ment is given to the machine carriage through theclutch-shaft m which carries at each end a worm n meshing with. anunderlying wormrgear n secured to a carriage-shaft a. Through this meansthe carriage may be moved under its own power along the rails in eitherdirection, according to the position of the clutch'm the same powerdriven member, namely, the shaft Z acting to swing the tool or advancethe carriage as may be required.

During cornercutting it is desirable to maintain the carriagestationary, and we have herein shown means for lifting the trucks of themachine clear from the track and there rigidly holding the machineduring the swinging movements of the tool. For this purpose there isprovided at each corner of the machine frame a lug O, which lugs arevertically threaded tolreceive the jack-screws 0 (Fig. 3) the latterhaving feet which aline with the top of the rails. The enlarged feet ofthese screws fit a socket in a split clamp 0, the two halves of whichmay be clamped securely to the under side of the tread of the rail bythe transverse clamping screw 0 VVhen the clamping screw is tightenedthe clamps grip the rail, preventing movement of the machine. Before'clamping, the jack-screws are turned to lift themachine high enough tofree the in the ordinary fashion with the supporting-frame held eithervertically or inclined backward for angle-cutting. The overhanging sideof the wall of the quarry, however, determines the limit of verticalcutting and when this is reached the machine is clamped to the rails,the worm gear turned to, tilt the cutter head forward at any desiredangle, and the tool then given, in addition to its usual reciprocatorymovement to and from the work, an oscillating movement as well throughany desired angle, so that the tool travelslengthwise the channel groovein an arc-like path and its blows are delivered radially from the centerof oscillation of the cutter-head. For example, referring to Fig. 2, themachine there shown is clamped to the rails B and engaged in mak-' ingthe corner cuts for a channel groove transverse to the previouslycompleted channel grooves 1, 2, 3 and 4, which with the exception of thegroove 1, have been out upon an angle. As represented in Fig. 2, thecutter-head has been swung forward by movement of the worm gear and isbeing oscillated by the tool-actuating engine L through the anglebetween the channel grooves 3 and 4, successive cuts being representedby the dotted arcs 5. After the too] has cut to the bottom of groove 3,the bottom of the new transverse groove is left flat or horizontally bystopping the return swing of the tool short of the full angle.

It will be seen that the described machine is quite universal in itsconstruction, and, the tool carrier being sustained at substantially 'amid position lengthwise the machine, so

that it may be forwardly inclined from either end, corner-cutting fromeither end. thereof, and at any angle which practical quarryrequirements demand, may be readily effected without necessary change inadjustment of the supporting frame H. The construction and shape of themachine furthermore permit its construction at a very low height, sothat it can be moved well into the corner of an inclined quarry wall.

The adjustment of the cutter-head to and from the work which ispermitted by the clamping-plates H permits the corner-cutting to bedone, particularly at extreme angles, with tools of much lesser length,since by this adjustmentthe' cross head may be brought, in substantiallythe same close relation to the rock in corner-cutting and angle cuttingas in upright cutting. This will a carriage. This 7 adj ustment' rendersthe tools easier to handle, as well as effecting a saving in their cost.For example, in the described machine a saving of 25 per cent. in theweight and length of the tools may be effected through this adjustmentwhen out ting at an angle of 34 for the corner of an upright cutapproximately six feet deep. This adjustment, inasmuch as it lowers thestandard (see Fig. 2) also decreases the height of the machine whencorner-cutting, permitting it to be advanced further into the corner.

While we have shown and described one form of our invention for thepurpose of illustrating the same, it is to be understood in details ofconstruction and relative arrangement of parts, as well as theapplication here made of the invention,the described embodiment may bewidely deviated from without departing from the spirit of the invention.
